<p>The object is to gently stop a pull-in member and to prevent a large impact force from being exerted on the pull-in member or a member disposed near the pull-in member and affected by the pulling-in operation of the pull-in member even when the pull-in member is pulled in by a pre-tensioner until the pull-in member is stopped. When a wire (3) is pulled by operation of a buckle pre-tensioner (11) at the time of an emergency, a buckle (2) is pulled in towards a bracket (1) while a cover (4) contracts. Before the cover (4) contracts to a maximum permissible contraction position, the buckle (2) comes into contact with the free end of a shock absorbing member (14), and, then, is pulled in while the shock absorbing member (14) is caused to contract. By the contraction of the shock absorbing member (14), the shock absorbing member (14) absorbs impact energy of the buckle (2), so that shock performance is further enhanced, and the buckle (2) can more effectively come into contact with the free end of the shock absorbing member (14) and can be gently stopped. <IMAGE></p> |
